Patented Mar. 3, 1914.

Application filed June 12, 1909. Serial No. 501,852. V

T all whom it may concern:

. Be it known that I, OT o PETERMANN, a. citizen of the Republic of Switzerland, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a full,

clear, and exact description.

This invention relates more particularly to the line-lock mechanism of a foldable front strike or visible type-writing machine.

The primary object of the invention is to provide simple and efiicient means serving as a line lock to adapt the machine to stop the carriage at a certain point in its movement across its support, and to permit the carriage to be quickly released for the purpose of adding an additional character or characters at the end of a line and then again lock the carriage against further movement as is often required to divide properly a word at the end of a line and at the same time to prevent the carriage from moving too far when the keys are operated.

A further object of the invention is to provide a machine in which the platen, carriage and line-lock mechanism may be moved vertically to different distances to adapt the type-heads to have a plurality of characters thereon, and the carriage support and mechanism mounted thereon folded over above the keyboard so that the machine will ogupy less space than when in use in case it is desired to transport the machine or for other purposes.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description. a

In the drawings, Figure 1 is a fragmentary vertical section, partly in elevation, of one form of machine embodying my invention. Fig. 2 is a fragmentary rear elevation. Fig. 3 is a detail perspective view of a device forming a part of the line-lock mechanism. Fig. 4 is a fragmentary sectional inverted plan showing in elevation the line-lock lever. Fig. 5 is an inverted plan view of the carriage support removed from the machine; and Fig. 6 is a fragmentary side elevation of the upper part ofthe machine.

The machine hereinafter set forth is of the type shown in the patent to Frank S. Rose, No. 754,242, patented March 8th, 1901, in'which the carriage is adapted to be folded over above the keys, and while in the present inventio-nthe carriage and platen and their operating mechanisms are adapted to be raised and lowered on the frame of the machine and to be folded keys, and in which the type-bars have a front strike for visible wr1ting, it is to be understood that the features of this invention may be used in connection with other classes of machines.

The metallic frame 25 Figs. 1 and 2, of the machine'is constructed and arranged in any suitable manner, and may consist of side members and an integral back member with an intermediate transverse horizontal bar 26 suitably fastened to the sides of the frame and serving as a brace therefor, the whole frame being constructed of sheet metal with rounded edges for the purpose of making the frame light and strong.

-.Any suitable platen and means for supporting the same may be employed. As shown the platen 27 is of the usual form and is mounted at its ends to rotate in the frame 28 of'a carriage 29. The carriage 29 moves along a normally fixed member, bed or support 30) and has a movable member 31 which is oppoded to the fixed support or bed 30, and said members form race-ways in which are arranged balls 32 forming a bearing for the member 31 of the carriage.

Various means may be employed for feeding the carriage for letter-spacing and as the escapement mechanism therefor. As shown the carriage is provided with a rack-bar 33 which extends lengthwise of the carriage and meshing with said rack-bar is a pinion 34, Fig. 1, and this pinion is held to rotate on a shaft 35 projecting under the carriage bed or support 30 to the lower end of which is held a ratchet wheel 36. This ratchetover above the finger wheel 36 forms a part of the escapement mechanism 37 and is located above the bracket or plate 38 in which one end of the shaft 35 is journaled, the ratchet wheel 36 being held to rotate with the shaft 35, and

.adapted to engage the ratchet wheel is an escapement device or lever 39. This lever or device 39 comprises two parts or members 40 and 11, and carried by the member or part 41 are the pawls 42 and 4.3, Fig. 5,

a rotary ters at the end of a line if desired. A bar I tain of these teeth is a pendant arm 47.v

the former of which is fixed and the latter loose, and said pawls are adapted to engage alternately the teeth pf the ratchet wheel 36 to permit said ratchet wheel to rotate with a step-by-step movement. The carriage is moved in one direction by a spring, and the movement of the carriage transmits movement to the ratchet wheel 36 through the rack-bar 33 and pinion 34. The end of the member 40 of the lever 39 is in the path of a vertically movable bar 44, and this bar is operated by each of the keylevers, not shown, on their downward movement-in any suitable way to release the escapement, this feature as well as the way the-carriage is supported, elevated, and adapted to be folded over above the keyboard being of any desired, construction.

The carriage may be locked at the end of a line and may be permitted to move several spaces for the addition of one or more let- 45, Figs. 2 and 5, is pivoted at its ends in the carriage frame and is normally forced in one direction by a spring 46. This bar 45, Fig. forming a series of teeth, and engaging cer- This arm may be adjusted along the bar 45, and is provided with ribs 47 'on opposite sides of its outer part adapted to fit between the teeth of the bar, and with a part 47 that spans the opposite side of the bar to detach ably clamp the armthereto. As the carriage travels forward the pendant arm 47 is adapted to engage the end 48, Figs. 4 and 5,

of a lever 49. This, lever 49 ispivoted at 49 to the fcarriage bed and is normally forcedrin -one direction by a spring 50, Figs. 2 and-4f=and the end 51 of said lever is provided with an outwardly-projecting pivoted member 52, and is made curved so as to extend adjacent to the end 53 of the arm 40 of the escapement lever 39. When the pendant arm 47 engages the end 48 of the lever 49, it will force the member 52 of the lever 49ovr the end 53 of the member 40 of the lever 39, thus preventing the vertically movingescapement releasing bar 44 from operating said escapement lever arm 40. As the lever arm or member 40 cannot be operated in this position by any of the keys, the

ratchet wheel cannot move, and this results in ho lding and locking the carriage against movement until the lever 49 is released. The lever 49 has a'second projecting portion 54 to provide a space between the part 54 and the end 48. so that when the. pendant arm 47 is released therefrom the carriage may be moved a distance according to the I length of the space between the ends or engaging parts 48 and 54 for the addition of letters at the end of the line and willthen be again locked by the arm 47 engaging the end 54 to force the lever 49 to a position to riage,

2, is provided with a plurality of slotslock the escapement lever 39 against move ment. The bar 46 has a lever 55 held thereto, Figs. 2 and 6, and this lever is provided with'a finger portion 56 by which the said bar may be quickly and conveniently moved on its pivot and the arm 47 released from engagement with the lever 49.

While I show certain features of a typewriting machine other than the present invention, as for example the escapement mechanism, this and other features not forming a part of the present invention, are claimed in separate and independent appli; cations filed by me; Q;- l

Having thus described my invention, I claim as new and desire to secure by Letters Patent l r.
